Enough talk of a journal, time to start one!! Here are the basic plans, some pictures, as well as my journal chronicling what has been happening over the past 9 days. Tonight they are being moved into their new bigger 23 L homes and I will have an updated post with pictures of the procedure soon. I wish everyone in the cup the best of luck and hope that I can provide both an informative and entertaining journal for all to read/view, and once again showcase the awesomeness of the Greenhouse Powderfeed! Peace GHSC Autoflower Cup Grow – 4 Strains – 6 plants Seeds: 2 x Super Critical Auto 2 x Sweet Mango Auto 1 x Northern Lights Auto 27/05/2013 - ** One NLA did not sprout so I am going to germinate 1 Big Bang Auto tonight. 1 x Big Bang Auto Growing media: Jiffy™ Peat starter pots – will transplant to 23 L pots once rooted in Jiffy’s 23 L pots - Pro Mix™ High Porosity/Grodan™ Growchunks/Hydrotron™ clay pellets @ approx. 40/40/20 mix Lighting: 18 hours on and 6 hours off entire grow Seedlings : 2 x Sunblaster™ T5 fluorescent - hung vertically on each side of the LED and angled towards the seedlings 1 x Sunshine Systems LED ** Lights will be kept a fair distance away as I am going for a mixed spectrum here not a ton of intensity Vegetation: 4 x 28W Sunshine Systems™ LED’s Flower: The 600W Hortilux Super HPS bulb w/cool tube reflector will be added once they are getting closer to flowering + 4 x LED’s Ventilation: Intake – (will be added once they are in the 23 L pots) via a 4 inch (10 cm), 176 cfm (300 M3/hr) Typhoon™ inline fan with a Mountain Air carbon filter attached on the intake end to provide some protection against fungi or bacteria etc. from entering the tent. This is new as so far I have relied only on passive intake, but I believe this could definitely improve yield. Extraction – via a 6 inch (15 cm), 280 cfm (475 M3/hr) CK™ inline fan with Mountain Air filter Water, Nutrients & Additives: Seedling transplant: All plants will receive Botanicare™ ZHO (Rhizosphere root inoculant w/trichoderma & mychorrizae) at transplant to 23 L pots Water & Nutrients: All plants will receive R/O (reverse osmosis) water + Botanicare™ Cal-Mag Plus and GHSC™ Mother’s Powderfeed once they are rooted and into 23 L pots until signs of flowering at which point they will be switched to the GHSC Hybrid Powderfeed. Unfortunately I don’t having any Indica powderfeed (other than 2 x 20 g sample packs that I will try out) which is recommended for autos but I was happy with the results once I started using the Hybrid feed last auto grow and hopefully using the Powderfeed from start to finish this time will only improve things. Additives will be used but not 100% sure which ones yet. And again, I will also use ZEO2™ CO2 producing pads for now, but am looking into other CO2 producing sources/methods for small spaces and this may change during the grow. 19/05/13 GERMINATION: Soaked seeds at 7:11 pm 19/05/13 in mineral water EC of 0.66, pH 6.8, temp @ 19 degrees to start, temperature should rise a few degrees. Glasses were placed in a box sealed from light and on top of the fridge where it will stay consistently warm. **EDIT** Having done more research, and having done this with the last Big Bang seed, I will in the future germinate with r/o water + tiny bit of Cal - Mag with EC no higher than 0.15, & pH @ 5.5. I was lazy and didn't pH and should have, and mineral water or not 0.66 is waay too high to germinate seeds considering they have all that they need in the seed to germinate. 20/05/2013 PLANTING: I opened the box 18 hrs later to find some seeds split their shell and others hadn’t. What is disturbing is that the water in each glass had a film on top of it L I used spring water that I’d opened a few months ago and sealed again, but with nothing persistent in the water to disinfect it (like chlorine in drinking water) something must have grown in it. I really should have known better with what I’ve learned in my water course in school and should have used fresh unopened spring water. I am hoping for the best but I fear the worst and I may need to purchase new seeds this coming weekend when I go to the Treating Yourself Expo in Toronto and start over if they don’t sprout into healthy little seedlings. Currently using one LED panel 18 inches directly above jiffys to germinate – with 2 x T5 Sunblaster fluorescents hanging vertically and angled towards the jiffy’s waiting to add mixed spectrum once they sprout and are a few days old. Once they are moved into their 23L homes I will have all 4 LED’s running until they are strong enough to add the 600W HPS Lights on 18 hrs: Room temp = 25 - 26°C rH = 55 % LED Light Height – 45 cm’s (18 inches) T5 = 23 cm’s (9 inches) from seedlings on the end Lights off 6 hrs: Room temp = 21°C rH = 65 % 21/05/13 No change 22/05/13 Today I added a heated seedling mat (* a new one, the old one would burn em up if not careful) to speed up the process a little I can see one SMA baby making her way up so far – I planted them a little deeper this time to help give them enough distance/friction to shed the seed and keeping them nice and moist while doing so. Having to spray and pry them off works but not always and having them worked off naturally is much preferred. @ 8:30 - one of each auto is showing signs of sprouting Lights on 18 hrs: Room temp = 23 °C Temp at base of jiffy pellets = 27 – 28 °C rH in room = 60 % average 23/05/13 @ 6 pm- approximately 77 hours after planting Sweet Mango Auto’s – both have split their shell and the bent stems are surfaced with cotyledons on their way up Super Critical Auto’s – Both have sprouted fully and look healthy Northern Lights Auto – one baby sprouted fully with healthy cotyledons, but 1st true leaves tips are looking white, I will keep an eye on her. The 2nd hasn’t shown signs of much yet so we will see. Watered - mixed new water: reverse osmosis w/small amount of Cal-Mag Plus EC = 0.4 pH = 5.5 Temp = 21 °C @ 8 pm - Now that almost all have sprouted and most have visible taproots I turned off heated mat, and turned on small ceramic oscillating heater to maintain proper temperature air temperature around 25 – 27. I want to get them into their new 23 L homes a lot quicker than the last autos and plan on transplanting them on Sunday or Monday most likely (in 3 – 4 days). Also started using the large humidifier to maintain target rH – around 65 – 70% for my set-up at this stage. Lights on 18 hrs: Room temp = 25 - 26 °C rH in room = 60 – 68 % 24/05/13 Status: Sweet Mango Auto’s – Both sprouted fully and with the exception of the very tips of the 1st true leaves looking a little white they look healthy. Super Critical Auto’s – Continue to grow 1st leaves and taller Northern Lights Auto – Still only the 1 baby sprouted outta 2, positive news is 1st true leaves looking more green and less brown and growing quickly. ** Going to buy a 5 pack of GHSC auto seeds this weekend, just not sure which ones yet, and may have 4 autoflower strains in the tent this time – maybe Big Bang? After time spent thinking about the cause of white tips on the first true leaves of some plants I considered that it is very unlikely that the autoflower seed-stock, especially of the new strains, would be very old and soaking them could create excess moisture causing the issue? Just a thought and maybe I’m wrong and it probably has to do with whatever was in the germination water – I’m sure these strong plants will fight anything nasty, crossing my fingers. LED Light Height = 40 cm’s (16 inches) Lights on 18 hrs: Room temp = 26 - 27 °C rH in room = 65-70 % Lights off 6 hrs: Room temp = 21°C rH = 65 – 70 % 27/05/13 – 4 days since sprouting Growth has been moving along nicely for the 5 babies. Second true leaves are already visible and the initial issues with white tips on some are already becoming a thing of the past. Taproots are visible as well as multiple feeder roots, especially on the Super Criticals. I’m going to wash up the 23 L pots tonight and transplant them in the next couple of days so as not to slow the rapid growth down. Tonight I’m also going to soak a Big Bang auto seed to take the place of the NLA seed that didn’t germinate, it’s my first try at growing 4 different strains together, and my first try at growing the Big Bang Auto last Auto grow I did 8 plants and 3 strains. Mixed new water: Reverse Osmosis (r/o) water +Cal Mag Plus to 0.4 EC + GHSC Mother’s Powderfeed to 0.6 EC total. pH = 5.6 Temp = 22 °C @ 10:45 pm – soaked a Big Bang Auto seed in r/o water + a few drops of Cal – Mag Plus = 0.20 EC & temperature @ 21 ° C. Placed in a light proof box in the grow room where it is about 25 – 26 °C LED Light Height = 35 cm’s (14 inches) T5 – 23 cm’s (9 inches) Lights on 18 hrs: Room temp = 25-27 °C rH in room = 65-75 % Lights off 6 hrs: Room temp = 22 °C rH = 70– 78 % 28/05/13 Planted a Big Bang auto seed after soaking it for 18 hrs in r/o water + Cal Mag Plus @ 0.30 EC & pH @ 6.0. Trying out a clear glass over top of the Jiffy to help improve rH and maintain a higher humidity around it until it sprouts. There are a number of gaps between the glass and the seedling tray which will allow some air exchange Noticed a few small orange/brown spots on the one Super C. auto and the Northern Lights auto. I don’t think it is anything serious and growth continues nicely. I am going to consider transplanting them tomorrow.

Hello everyone, First of all, as usual, I would like to thanks Green House Seeds, Strain Hunters and all the people handling this contest, you are doing an amazing job. This grow will be focused on Auto-Bomb (Green-O-Matic x Big Bang Auto) and Sweet Mango Auto (Mango x Big Bang Auto). Two different crosses of Big Bang Auto, I already grown it and I liked it, was a very fragranced fruity smoke. I’ll use a regular photoperiod for this grow even if they are autoflowering, so it will start at 18h/6h at 250W 6400K° CFL bulb, then still 18h/6h at 600W MH 5000K° bulb after 2 to 3 weeks, then when the first flowers are out 12h/12h at 600W HPS 2000K° bulb. I'll use BioBizz Light mix as soil in the pre veg/veg, then AllMix when I repot, and will start the feeding with Powder Feeding Short Flowering (same as Mostly Indica) after the pre veg.

Some are a bit faster, already some nice little flowers. 01-06-2013 - Day 52 from seed : Day : 26°C Night : 21°C Humidity 45-50% Fed this week at PH 6.2 EC 1.6, the tent start to fill up The tall Sweet Mango has stopped stretching (fortunately) 09-06-2013 - Day 60 from seed : Day : 27°C Night : 21°C Humidity 40-45% Fed at PH 6.3 EC 1.7 this week, I had to manage some hot temperatures, but they don't seem to be disturbed 16-06-2013 - Day 67 from seed : Day : 28°C Night : 23°C Humidity 40-45% Fed at PH 6.4 EC 1.8 This week. The Sweet Mangos are a bit faster than the Auto Bombs. On the pictures, the 4 in front are Auto Bombs, the 6 other are Sweet Mangos. They begin to gain weight, smell so good already. 23-06-2013 - Day 74 from seed : Day : 25°C Night : 21°C Humidity 40% Temperatures are back to normal, I fed them at PH 6.5 EC 1.8 this week and until final flush. The smell is more and more present, Sweet Mangos are still faster than the Auto Bombs. But Auto Bombs got "longer" buds. The 3 last pictures are Auto Bomb buds, all the other are Sweet Mango. 30-06-2013 - Day 81 from seed : Day : 25°C Night : 22°C Humidity 35-40% I did the last feeding this week at PH 6.5 EC 1.8 and will now start the final flush for 7 to 15 days at PH 6.5 EC 1.3, then EC 1.0. The leaves start to turn yellow, the end is near 07-07-2013 - Day 88 from seed : Day : 28°C Night : 23°C Humidity 35-40% I flushed them at PH 6.5 EC 1.3 then PH 6.5 EC 1.0. The fastest SMA has been flushed for 8 to 9 days and harvested today. The rest will follow this week or next week end. Harvest : - Sweet Mango : SMA 1 - Day 88 from seed. SMA 2 - Day 90 from seed. SMA 3 - Day 90 from seed. SMA 4 - Day 92 from seed. SMA 5 - Day 94 from seed. SMA 6 - Day 95 from seed. - Auto-Bomb : AB 1 - Day 92 from seed. AB 2 - Day 94 from seed. AB 3 - Day 95 from seed. Dry Stuff : - Sweet Mango : - Auto-Bomb : Dry Weight : SMA 1 : 26g SMA 2 : 33g SMA 3 : 38g SMA 4 : 34g SMA 5 : 30g SMA 6 : 32g AB 1 : 24g AB 2 : 24g AB 3 : 26g Powder Feeding Leaflet : For those who don't have it, maybe it can help. Click on a picture, then you can save it. Tips : Some tips for Auto Bomb and Sweet Mango Auto strains : -Auto Bomb : I noticed they react better if you water them with "cold" water. Because if you water them with tempered water (like 22°c), they may have the leaves dropping down after watering. 7 to 10 more days would have slightly increase the yield. -Sweet Mango Auto : React very well on both cool and tempered water. If you cut the lower branches you will have a big main bud so they react well to this. (But not recommended on a Auto). Smoke Report / Effects : -Auto Bomb : Hits strong and relaxing in same time, good for daytime if you are stressed or for bedtime. Fruity candy smell and taste. -Sweet Mango Auto : Hits strong, long lasting, good for daytime/bedtime. The smell is complex, Mango and milky sour fruits. Taste is like sour fresh mango, very fruity. Thanks for watching. -Peace.

Hey guys, welcome to my grow journal for the Outdoor World Cup! Originally i thought about starting this journal after my seeds arrived. But they are not here yet and it is June/15. I ordered the free kit with power feeding. So I do not know yet which strain i am going to get. But i can give you already some information about the equipment i will use for the seedlings and early vegetative phase indoor. Lets start with the room. My tent from Grow Lab is called GL 100. It has an area of 1 square meter (100cmx100cm) and is 2 meters tall. Inside there is a reflective foil everywhere. You have a lot of holes for you your air and water tubes or for cables. From the outside it is black and it offers you two windows to watch your plants while the tent is closed. Like that you can make sure that your air circulation stays as usual. The air circulation is made by a System Air RKV 200E2-A1 LTI as outtake that has about 770 m³/h. For the intake there is a small axial fan. The System Air fan is connected to a cooltube reflector called Sputnik. I have the large one with a 150mm connector. This reflector is really awesome. It is cool and really big. The surface is covered with a nice reflective material. Compared to other reflectors the Sputnik offers the most light in the middle of the reflector. It has the perfect size for 1 m². The reflector is already a nice tool to keep the temperature low. But for the perfect adjustment I use a G SE Fan Controller that offers me to the fan speed, the temperature, the humidity and the negative pressure. The intake fan as well as the outtake fan are connected to it. The electrical power for the light inside the reflector comes from a Lumatek ballast. The Lumatek is one of the new generation ballasts that are more efficient and allow you to change the W. In my case i can switch between 400W, 400W SL, 600W and 600 W SL. SL means Super Lumen and should increase the power by 10%. So it is 400W, 440W, 600W, 660W. The ballast will run a 400W MH light with 440W/400W LS. The soil i use is called BioBizz Light Mix. Allright! That´s my setup! Now I have to wait for the seeds! As soon as they arrive i will start germinating them. And ofcourse i will take pictures and use them in my next update for you guys! Feel free to comment and to ask questions! aeroguy

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
